REAR AXLE General Information27-2
GENERAL INFORMATION
The rear axle is a banjo-type semi-floating type andprovides the following characteristics: The rear wheel bearing is of an anti-mud
enhanced type. In order to improve driveability at muddy road,
helical LSD are available as optional equipment.
For vehicles with ABS, the ABS rotor ispress-fitted to the axle shaft.
In order to improve stream-crossingperformance, a vent plug is fitted to the upperpart of the axle housing.

ON-VEHICLE SERVICE
REAR AXLE TOTAL BACKLASH CHECK
1. Place the transmission shift lever and the transfer shiftlever in the neutral position, apply the parking brake andthen jack up the vehicle.
2. Manually turn the propeller shaft clockwise as far as itwill go and make mating marks on the companion flangedust cover and the differential carrier.
3. Manually turn the propeller shaft anti-clockwise as far as itwill go and measure the movement of the mating marks.
Limit: 4.2 mm
4. If the backlash exceeds the limit, remove the differentialcarrier assembly, and then carry out the following checks.Final drive gear backlash (Refer to P.27-16.)Differential gear backlash (Refer to P.27-16.)

4. Install the filler plug, and then tighten it to the specifiedtorque.
Tightening torque: 49 Nm
WHEEL BEARING AXIAL PLAY CHECK
1. Place a dial gauge against the axle shaft as shown inthe illustration, and then move the axle shaft in the axialdirection and check the axial play.
Limit: 0.025 mm
2. If the axial play exceeds the limit, check the backing plateto axle housing tightening torque. If it is correct, replacethe bearing.

5. If the differential gear backlash exceeds the limit, adjustthe backlash by replacing the side gear spacers.
6. If adjustment is not possible, replace the side gears andpinion gears as a set.
7. After adjustment, check that the backlash does not exceedthe limit and the differential gear turns smoothly.
F DRIVE GEAR INSTALLATION
1. Clean the drive gear attaching bolts.2. Remove the adhesive adhered to the threaded holes of
the drive gear by using a tap, and then clean the threadedholes by applying compressed air.
3. Install the drive gear onto the differential case with themating marks properly aligned.
Tightening torque: 78 88 Nm
GSIDE BEARING INNER RACE INSTALLATION
Use the special tool to press-fit the side bearing inner racesinto the differential case.
HBEARING CAP INSTALLATION
Install the bearing caps with the mating marks properly aligned,and then tighten the bearing caps installation bolts to thespecified torque.
I DRIVE GEAR BACKLASH ADJUSTMENT
Adjust the drive gear backlash by the following procedures:1. Use the special tools to tighten the side bearing nut to
the position where a preload will start to be applied tothe side bearing.

2. With the drive pinion locked in place, measure the drivegear backlash with a dial indicator on the drive gear.
NOTEMeasure at four points or more on the circumference ofthe drive gear.
Standard value: 0.08 0.13 mm
3. If the drive gear backlash is not within the standard value,use the special tools (MB991367 and MB991385) to tightenor loosen the side bearing nuts as shown in the illustration,in order to adjust the backlash.
NOTEFirst loosen the side bearing nut, then tighten the sidebearing nut the same amount as when it was loosened.
4. Use the special tools to turn down both right and left sidebearing nuts on half the distance between centres of twoneighboring holes, in order to apply the preload to theside bearing.
5. Measure the drive gear runout at the shoulder on thereverse side of the drive gear.
Limit: 0.05 mm
6. If the drive gear runout exceeds the limit, reinstall bychanging the phase of the drive gear and differential case,and remeasure.
7. If adjustment is not possible, replace the differential caseor limited slip differential case, or replace the drive gearand drive pinion as a set.
8. Select either of the lock plates, and then install it.9. Check the drive gear tooth contact. If poor contact is
evident, adjust the drive gear tooth contact. (Refer toGROUP 26 Differential carrier.)

OUTLINE OF CHANGE
The rear differential reduction gear ratio has been changed due to the introduction of 2000-mL engine. A rear stabilizer bracket has been added to the rear axle housing due to the introduction of the rear
stabilizer bar. Because of this, the service procedure has been added.
